For any work activities involving dangerous substances, this is the main risk assessment module in DSEAR and there are several guidance documents to assist in the process of area classification.
Typical sinage and informtion.

The various areas within a DSEAR Site must be appropriately identified and signage must be in use where personnel have access to hazardous areas.


Pedestrian access..

Typically, where pedestrian acces is needed then an example sign might be as shown here.

DSEAR Regulations 2002 on site assessment evaluation, area classification, explosion protection documents and site audits, ATEX equipment certification and approvals

Provide measures to eliminate or reduce, so far as reasonably practicable,the risks

Risk evaluation is of primary importance, as this assists in removing unnecessary processes and functions from the hazardous areas, so minimising the impact on plant and equipment.

Classify and zone places where explosive atmospheres may occur


Where hazardous areas do remain then any equipment which may present a hazard that will be used within it must be assessed, approved or certified in some measure, depending upon the severity of the risk.

Provide equipment and procedures to deal with accident and emergencies

Many hazardous sites are themselves located along side other dangerous sites and may even be close to residential areas.

The regulations require companies to put in place sufficiently robust accident and emergency procedures to deal with any event should it arise.This may involve outside agencies, such as fire authorities, police, emergency services etc..

Provide information and training to employees



Identification of pipes and containers where these contain dangerous substances

One of the main areas in the regulations is the process of identification, where a flammable substance or hazardous situation may occur

Then it is important to identify these areas, along with any residual risk areas identified in the risk assessment.

Therefore appropriate signage must be used.

Duty of coordination

A key area of the regulations is the requirement for the duty of co-ordination, which involves establishing the correct protocols within a company to manage the risk.

This includes training staff, liasing with senior management and outside agencies thus ensuring a central point exists with the company where information may be obtained.
